Re: Steep drop in prices for SSD
Backups are not just for disaster recovery - they are also critical in servicing that call "Ooops, I've just deleted that file I need - can you get it back". A filesystem that supports snapshots (e.g. ZFS) services this need rather nicely.
"it's a pain in the ass to restore from backups" - that means you are doing it wrong. From an estate of
50TB I reckon to restore a file or set of files of varying vintage, going back a few years, within a few minutes.
It's important to remember that the call to restore from backup is going to under duress at any time of day or night, so needs to be straightforward.
